The Lowdown
Right, surfers, Rusty here. Let’s get into it. We’ve got a solid run of good surf coming up at Lakey Pipe, a consistent reef break that’s exposed to the SW. The water temp is about average for the time of year, nothing wild there.
The week kicks off with a decent pulse. Thursday morning the 27th sees a clean 4ft SW swell with a long 16-second period, giving the waves real shape and push. The cross-offshore breeze from the SE keeps things clean. The combined energy is moderate at 932, but it’s a nice start. By Thursday afternoon, the energy jumps to 1505 and the swell holds, still excellent for experienced surfers.
Friday the 28th is the real standout. That morning, the swell pumps up to 8ft from the SW, with a 17-second period, and the combined energy is a very strong 4343. It’s a big, powerful groundswell. The wind stays cross-off, keeping it clean. This is expert territory right here – not for the faint-hearted. The afternoon holds similar size and quality.
Saturday the 29th is still solid, with 7ft SW swell in the morning, though the period drops a touch to 16 seconds. Energy is still strong at 2246. The wind remains light and cross-off, so it’s still clean. Sunday the 30th eases a bit, with 5ft to 5ft SW swell, but still plenty of fun.
Monday the 31st shows a bit of a weird one. The morning has a 4ft SW swell with a very long 19-second period. That long period, combined with the moderate energy of 1391, means the waves will be powerful but with long lulls between sets. The tide might be a factor too. The afternoon picks up to 5ft and 18 seconds, cleaner.
The first couple of days of September bring a stronger, more consistent SW swell. Tuesday the 1st and Wednesday the 2nd see 7ft to 7ft SW swell, with 18-second periods, and energy in the strong 2500–2900 range. The wind is a moderate breeze, still cross-off, but the wave comment mentions marginal tide conditions, so you’ll need to pick your sessions.
The best part of the second week looks like the 6th and 7th of September. Sunday the 6th has a clean 7ft to 7ft SSW swell with a 16-second period, light breeze, and strong energy around 2000. Monday the 7th is similar, with 6ft SW swell. The following week keeps cooking, with Wednesday the 9th and Thursday the 10th of September both showing 8ft to 8ft SSW swells, 16-second periods, and very strong energy over 3000. The wind is light and cross-off, making for epic conditions for those who can handle it.
Keep in mind, Lakey Pipe is a reef break, and it’s often crowded, so expect company out there. The long-period swells (over 15 seconds) will be best here, as the reef handles the energy beautifully. Overall, the run from the 28th of August through the 10th of September is the clear winner, with Friday the 28th and Wednesday the 9th being the absolute best on offer.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
